１６例静脉性阳萎在海绵体血管活性药物注射后，采用双功能彩色多普勒超声（ＤＣＤＳ）来监测血流动力学变化，并用３２例功能性阳萎作对照组。背深动脉监测指标：１．舒张期内径（ＡＤ），２．最大收缩期流速（ＰＳＶ），３．舒张末期流速（ＥＤＶ），４．阻力指数（ＲＩ），５．血流加速度（ＡＣＣ）。背深静脉监测指标：１．静脉内径（ＶＤ），２．血液流速（ＶＶ）。研究结果提示静脉性阳萎ＥＤＶ＞Ｏｃｍ／ｓｅｃ，ＲＩ＜１，均Ｐ＜０．０１。背深静脉显示持续性、高流速血液回流。我们认为采用ＤＣＤＳ监测对客观评估静脉性阳萎血流动力学变化和静脉性阳萎的诊断均有一定价值。
16 cases of venous impotence After spontaneous vasoactive drug injection, hemodynamic changes were monitored by dual-function color Doppler ultrasound (DCDS), and 32 cases of functional impotence were used as the control group. Dorsal artery monitoring indicators: 1. Diastolic diameter (AD), 2. Maximum systolic velocity (PSV), 3. End-diastolic velocity (EDV), 4. Resistance Index (RI), 5. Blood flow acceleration (ACC). Dorsal vein monitoring indicators: 1. Intravenous diameter (VD), 2. Blood flow velocity (VV). The results suggest that venous impotence EDV> Ocm / sec, RI <1, both P <0.01. Dorsal deep vein showed persistent, high-velocity blood reflux. We believe that the use of DCDS monitoring of objective evaluation of venous impotence hemodynamic changes and venous impotence diagnosis is of some value.
